Intramolecular interactions in a new tris-dithizonatocobalt(III) complex

Electrochemically Co(HDz)3 (5), show three main ligand-based redox processes, two reductions and one oxidation. Ligand oxidations can be resolved into three components highlighting effective intramolecular interactions between molecular fragments; a spectroelectrochemical study of (5) highlighted spectroscopic changes during the six observed redox steps.
